Question

Find the area of the trapezoid. A drawing of a trapezoid with length of two parallel sides equal to a mixed fraction of one and a half centimeters and three and a half centimeters. The altitude of the trapezoid is 4 centimeters.

Answer 1

Answer:

$10cm^2$

Step-by-step explanation:

We are given that

Two parallel sides of trapezoid are

$a=1\frac{1}{2}cm=\frac{3}{2}=1.5cm$

$b=3\frac{1}{2}=3+0.5=3.5 cm$

Height of trapezoid, h=4 cm

We have to find the area of the trapezoid.

We know that

Area of trapezoid=$\frac{1}{2}(a+b)h$

Where a and b are two parallel sides

h=Height of trapezoid

Using the formula

Area of trapezoid=$\frac{1}{2}(1.5+3.5)\times 2$

Area of trapezoid=$10cm^2$
