finlep [7]

Firstly, we will draw figure

now, we will draw a altitude from B to DC that divides trapezium into rectangle and right triangle

because of opposite sides of rectangle ABMD are congruent

so,

DM=AB=9

CM=CD-DM

CM=18-9

CM=9

now, we can find BM by using Pythagoras theorem

BM=\sqrt{BC^2-CM^2}

now, we can plug values

we get

BM=\sqrt{15^2-9^2}

BM=12

now, we can find area of trapezium

A=\frac{1}{2} (AB+CD)*(BM)

now, we can plug values

and we get

A=\frac{1}{2} (9+18)*(12)

A=162cm^2

so, area of of the trapezoid is 162cm^2..........Answer

I'm really confused on this one please answer !!!!!!!
Sedbober [7]
The formula for finding the area of a rug: A = s^2

Plugging in the values we know, we can solve for s.

79 = s^2

Take the square root of both sides.

\sqrt{79} = s

\sqrt{79} is approximately equal to 8.89

So, 8.89 feet is the answer.
