Question

Find the area of a triangle whose base is 8 inches and whose height is 12 in.

(a) 96in.²
(b) 10in ²
(c) 20in.²
(d) 48in.²​

Answer 1

d

Explanation:

area= ½ × b × h

= ½ × 8 × 12

= ½ × 96

= ⁹⁶/²

= 48in²

Answer 2

48in.²

Explanation:

The formula for the area of a triangle is 1/2 x b x h

Since the b = 8 and the h = 12, substitute 8 and 12 for b and h.

1/2 x 8 x 12

4 x 12

48in.²
