Question

find the area of triangle whose base is 30 cm and height is 18 centimetre

Answer 1

as we know that

area of triangle = 1/2 × base × height

= 1/2 × 30 × 18

= 30 × 9

= 270

so area of triangle is 279 cm^2

Answer 2

area of triangle = half × base × height
b= 30 cm
h =18 cm
since, =1/2 ×30×18
= 270 cm²
