What is the area of this composite figure?
Mkey [24]

We have two congruent trapezoids.

The formula of an area of a trapezoid:

A=\dfrac{base_1+base_2}{2}\cdot\ height

We have:

base_1=210\ mm\\\\base_2=150\ mm\\\\height=55\ mm

Substitute:

A=\dfrac{210+150}{2}\cdot55=\dfrac{360}{2}\cdot55=180\cdot55=9,900\ mm^2

Answer:

2A=2\cdot9,900\ mm^2=19,800\ mm^2

Find the area of a square if the perimeter is equal to 38 in.
Misha Larkins [42]
Hello! I would love to help!

Alright! We know that perimeter is basically adding all the sides of a shape together. We also know that a square has 4 sides, so 38 is the result of 4 sides being added. Now, we also know that all sides of a square are even. So, to find one side of a square, we just need to do 38/4


38/4=9.5


Alright. So now we know one side of a square is 9.5 in. We know that in order to find area, we have to multiply length and width. We know that since all sides of a square are even, 9.5 is both our length and width. So, in order to find the area, we just have to multiply 9.5 by 9.5

9.5*9.5=90.25

Alright! So we have determined your answer!!!


90.25 or in fraction form 90 1/4 inches squared!

Hope this helped! Comment if you have questions!!
