Question

A trapezoid with a height of 8 feet and one base measuring 11 feet has an area of 112 square feet. find the length of the other base

Answer 1

24. you are supposed to multiply 8x11 then add the other length. so, 8x11=88then add 24 which equals 112. Hope this helps! 

Answer 2

Answer:

17 feet

Step-by-step explanation:

Area of Trapezoid is given by:

$A = \frac{a+b}{2}\times h$

Where, a and b are two bases, h is the height.

Given:

a = 11 feet

h = 8 feet

A = 112 square feet

b= ?

⇒$112=\frac{11+b}{2}\times 8\\ \Rightarrow 112=4 (11+b)=44+4b\\ \Rightarrow 4b = 68 \Rightarrow b = 17$

Thus, the length of the other base would be 17 feet.
