Fresh day khusioli, let's solve. Question 11: Based on the measurements provided in the figure: AB = 2.7 cm BC = 1.5 cm The total length AD = 4.5 cm. We can find CD by subtracting AB and BC from AD: CD = AD - AB - BC = 4.5 - 2.7 - 1.5 = 0.3 cm. Also, we can find AC and BD: AC = AB + BC = 2.7 + 1.5 = 4.2 cm BD = BC + CD = 1.5 + 0.3 = 1.8 cm Step 1: Calculate the required lengths using the given measurements. *a) AB + BC AB + BC = 2.7 cm + 1.5 cm = 4.2 cm *b) BC + CD BC + CD = 1.5 cm + 0.3 cm = 1.8 cm *c) AC - BC AC - BC = 4.2 cm - 1.5 cm = 2.7 cm *d) BD - CD BD - CD = 1.8 cm - 0.3 cm = 1.5 cm Question 12: Based on the measurements provided in the figure: PQ = 1.8 cm QR = 1.5 cm RS = 1.6 cm
