Question

8 cmA = 72 cm8 cm7 cmh16 cmfind the height of h of the trapezoid

Answer 1

Data:

A=72cm^2

Base 1= 8cm

Base 2= 16cm

As the area of a trapezoid is:

`A=(1)/(2)(b_1+b_2)\cdot h`

Where:

A is the area

b1 is base 1

b2 is base 2

h height

You use the formula of the area to clear the value of the h, as follow:

1. You substitute the values you know (A b1 and b2):

2. You do the addition (8cm+16cm):

3. You
