I NEED HELP IMMEDIATELY ITS FIND AREA AND OF L SHAPE HELPP FOR BRAINIST THINGY AND 20 POINTS !!

Rectangle 1: 84 ft^2   Rectangle 2: 8 ft^2

Step-by-step explanation:

Split the figure into two rectangles

Rectangle 1:

Width of rectangle 1 can be found by subtracting 8 ft from 15 ft

15-8=7 ft (width)

length is already given as 12 ft

So,

A = L x W

A = 12ft x 7 ft

A = 84 ft^2

Length is already given of one of the rectangles

Rectangle 2:

Finding the width of Rectangle 2 can be found by subtracting 11 ft from 12 ft to find the length of that dashed line or the width of rectangle 2.

12 ft - 11 ft = 1ft (width)

Length: 8 ft

Width: 1ft

A=l x w

A=8 x 1

A=8 ft^2

14x-32

Step-by-step explanation:

JL = JK+KL

JL = 5x-2+9x-30

JL = 14x-32
