Question

Draw an isosceles trapezoid (A trapezoid with two equal, non-parallel sides) label the top base 6 cm in the height 4 cm if the area of the trapezoid is 36 cm² what is the length of the other base

Answer 1

12

Explanation:

Givens

b2 = 6 cm

h = 4 cm

Area = 36 cm^2

Formula

Area = (b1 + b2)*h/2

Solution

(6 + b2) * 4/2 = 36 cm

(6 + b2) * 2 = 36 Divide both sides by 2

(6 + b2) = 36/2

(6 + b2) = 18 Remove the brackets

6 + b2 = 18 Subtract 6 from both sides

b2 = 18 - 6 Combine

b2 = 12
