Question

The formula for the area of a triangle is a=1/2bh. solve the formula for h. a triangle has a base of 7cm and an area of 28cm squared. what us it's height

Answer 1

28=1/2(7)h
Divide by 7 on both sides giving you
4=1/2h
Multiply by 2 on both sides giving you
h=8
Therefore, the height is 8cm.

Answer 2

Answer: 8 cm

Step-by-step explanation:

Given : The formula for the area of a triangle is $a=\dfrac{1}{2}bh$

If a triangle has a base of 7 cm and an area of 28 cm squared.

The substitute the values of b = 7 and a = 28 in the above formula, we get

$28=\dfrac{1}{2}(7)h$

Divide 7 and multiply 2 on on both sides, we get

$h=\dfrac{28\times2}{7}=4\times2=8\ cm$

Hence, the height of triangle = 8 cm
