Question

Match the following triangles with their respective areas.

• A. 39 cm${}^2$
• B. 63 cm${}^2$
• C. 48 cm${}^2$

Answer 1

Area of triangle = $\frac{1}{2}(base\times height)$

$\therefore$Area of $△$RAT = $\frac{1}{2}(14cm\times 9cm)$

$=\frac{1}{2}\left(126c{m}^2\right)$

$=63c{m}^2$

Area of $△$CAT = $\frac{1}{2}(13cm\times 6cm)$

$=\frac{1}{2}\left(78c{m}^2\right)$

$=39c{m}^2$

Area of $△$FAT = $\frac{1}{2}(12cm\times 8cm)$

$=\frac{1}{2}\left(96c{m}^2\right)$

$=48c{m}^2$
