Haya, tuendelee na maswali haya ya hesabu:

Mume ana miaka 7 zaidi kuliko mke.
Umri wa mume = Umri wa mke + miaka 7

$$25 + 7 = 32$$

Umri wa mume ni miaka 32.

$$\boxed{\text{Miaka 32}}$$

b) What is their total age?

$$32 + 25 = 57$$

Jumla ya umri wao ni miaka 57.

$$\boxed{\text{Miaka 57}}$$

c) How old will the man be 3 years from now?

Baada ya miaka 3, umri wake utakuwa:

$$32 + 3 = 35$$

Mume atakuwa na miaka 35 baada ya miaka 3.

$$\boxed{\text{Miaka 35}}$$

27. The diagram below shows a rectangular flower garden.

a) Find the value of;
Katika mstatili, pande zinazoelekeana zina urefu sawa.

$$b = 8 \text{ cm}$$

Thamani za $a$ na $b$ ni:

$$a = \boxed{10 \text{ cm}}$$ $$b = \boxed{8 \text{ cm}}$$

b) Calculate the area of the flower garden.

Urefu = 10 cm
Upana = 8 cm

$$\text{Eneo} = \text{urefu} \times \text{upana}$$ $$\text{Eneo} = 10 \text{ cm} \times 8 \text{ cm}$$ $$\text{Eneo} = 80 \text{ cm}^2$$

Eneo la bustani ya maua ni $80 \text{ cm}^2$.

$$\boxed{80 \text{ cm}^2}$$
