Answer 1

Answer: 20 yards.

Step-by-step explanation:

To find the area of the shaded region (in blue), first find the area of the right triangle and the rectangle.

Rectangle.

Use $a = lw$ (area = length x width) since you are already given the values

$a = lw = 3*4=12$

Right triangle.

Use $a= \frac{1}{2} ab$ to find the area of a right triangle, in which a and b are legs (not the hypotenuse.

$a = \frac{1}{2} ab = \frac{1}{2} *8*8 = 32$

Subtract the area of the rectangle from the right triangle to find the area of the shaded region.

$32-12=20$

The answer is 20 yards.

Answer 2

Answer:

20 yd²

Step-by-step explanation:

This problem is really easy once you break it down!

First, find the area of the triangle.

$A = \frac{1}{2}bh$

b = 5 + 3 = 8

h = 4 + 4 = 8

$A = \frac{1}{2}*8*8$

$A = 32$

Now find the area of the square.

$A = lw$

$A = 4*3$

$A = 12$

The last step is to subtract.

Area of triangle - area of rectangle =

32 - 12 = 20

20 yd²
