Answer: 4in.
Step-by-step explanation:
We have several formula for finding the area of a triangle. But with this, since it involves the base and the height, we use
Area of triangle. = (1/2)bh, where b = base and h = height. The area us given and the height, to find the base, we now equate the formula above with the value which is 10 and find the base. Now
(1/2) x b x h = 10in²
b x h = 20
b x 5 = 20
5b. = 20
Therefore,
b = 4in.
