Here are the solutions for the remaining questions: Question 1: A rectangle has a length of 12\, cm and a width of 6\, cm. Step 1: Write the formula for the area of a rectangle. The area of a rectangle (A) is given by the formula: A = length × width Step 2: Substitute the values of length and width into the formula. A = 12\, cm × 6\, cm Step 3: Calculate the area. A = 72\, cm^2 The area of the rectangle is 72 cm^2. --- Question 2: A triangle has a base of 18\, cm and a height of 6\, cm. Step 1: Write the formula for the area of a triangle. The area of a triangle (A) is given by the formula: A = (1)/(2) × base × height Step 2: Substitute the values of the base and height into the formula. A = (1)/(2) × 18\, cm × 6\, cm Step 3: Calculate the area. A = 9\, cm × 6\, cm A = 54\, cm^2 The area of the triangle is 54 cm^2. --- Question 6: A rhombus has diagonals of 12\, cm and 16\, cm. Step 1: Write the formula for the area of a rhombus. The area of a rhombus (A) is given by the formula: A = (1)/(2) × d_1 × d_2 where d_1 and d_2 are the lengths of the diagonals. Step 2: Substitute the values of the diagonals into the formula. A = (1)/(2) × 12\, cm × 16\, cm Step 3: Calculate the area. A = (1)/(2) × 192\, cm^2 A = 96\, cm^2 The area of the rhombus is 96 cm^2. --- Question 8: A sector of a circle has a radius of 14\, cm and an angle of 90^. Step 1: Write the formula for the area of a sector. The area of a sector (A) is given by the formula: A = ()/(360^) × r^2 where is the central angle and r is the radius. We will use = (22)/(7). Step 2: Substitute the values of , , and r into the formula. A = (90^)/(360^) × (22)/(7) × (14\, cm)^2 Step 3: Simplify the fraction and calculate the square of the radius. A = (1)/(4) × (22)/(7) × 196\, cm^2 Step 4: Perform the multiplication. A = (1)/(4) × 22 × 28\, cm^2 A = 1 × 22 × 7\, cm^2 A = 154\, cm^2 The area of the sector is 154 cm^2. All done with this set!
