A tabletop in the shape of a trapezoid has an area of 8,820 square centimeters. Its longer base measures 135 centimeters, and the shorter base is 105 centimeters. What is the height?

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

im pretty sure it's 4 beacsue 8/2 equals 4

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
