Question

20 m

7 m
9 m
10 m

Find the area of the triangle (A = 1/2bh)

A 140 m2
B. 90 m2
OC. 46 m2
O D. 35 m2
O E 39 m2

Answer 1

D

Explanation:

The area (A) of a triangle is calculated as

A =
`(1)/(2)` bh ( b is the base and h the perpendicular height )

Here b = 10 and h = 7 , then

A =
`(1)/(2)` × 10 × 7 = 5 × 7 = 35 m² → D

Answer 2

D) 35m is the answer
