Question

find the area of triangle whose base and atitude are 15 cm and 6cm respectively ​

Answer 1

Area of triangle=1/2× base × height

Area of triangle=1/2×6×15

Area of triangle=3×15

Area of triangle= 45

Answer 2

Base (b) = 15 cm

Altitude (h) = 6 cm

Therefore, area (A) =

$\frac{1}{2} \times b \times h \\ = \frac{1}{2} \times 15 \: cm \times 6 \: cm \\ = 15 \: cm \times 3 \: cm \\ = 45 \: {cm}^{2}$
