pashok25 [27]

The height of purse which is in trapezoid shape is 26 cm

<em><u>Solution:</u></em>

Clara has a purse in the shape of a trapezoid

<em><u>The area of trapezoid is given by formula:</u></em>

Area = \frac{a+b}{2} \times h

Where,

"h" is the height

From given,

Area = 754 cm

a = 22 cm

b = 36 cm

h = ?

<em><u>Substituting the values in formula,</u></em>

754 = \frac{22+36}{2} \times h\\\\754 = \frac{58}{2} \times h\\\\Simplify\ the\ above\ expression\\\\754 = 29h\\\\Divide\ both\ sides\ of\ equation\ by\ 29\\\\h = 26

Thus height of purse which is in trapezoid shape is 26 cm
