For this one, instead of breaking it down into 3 shapes we can simply subtract the missing square area from the total enclosing area...

15*8-4*4

120-16

104 cm^2

Answer:

95\ cm^{2}

Step-by-step explanation:

we know that

The area of the figure is equal to the area of the whole rectangle minus the area of the smaller square

<u>Find the area of the whole rectangle</u>

The formula to calculate the area of rectangle is equal to

A=bh

where

b is the base

h is the height

we have

b=8\ cm

h=15\ cm

substitute

A=8*15=120\ cm^{2}

<u>Find the area of the smaller square</u>

The formula to calculate the area of the square is equal to

A=b^{2}

where

b is the length side of the square

we have

b=15/3=5\ cm

substitute

A=5^{2}=25\ cm^{2}

<u>Find the area of the figure</u>

A=120\ cm^{2}-25\ cm^{2}=95\ cm^{2}

Please HELP!!!!! I need to know the missing value. PLease!!!!!!!!!!!!!!

Answer:

w = 21.4 ft

Step-by-step explanation:

Area of Trapezoid = Area = (a+b)/2 * h

Where a and b are the bases of trapezoid, and h is the height.

In the figure we are given:

a= 32.3 ft

b=w=?

h= 22.9 ft

Area = 614.865 ft²

Putting values in formula

Area = (a+b)/2 * h

614.865 = (32.3 + w) / 2 * 22.9

1229.73 = 32.3 + w * 22.9

1229.73 / 22.9 = 32.3 +w

53.7 -32.3 = w

=> w = 21.4 ft
