I need a step by step explanation but I’d be ok with the solution.

169. (m^2)

Step-by-step explanation:

lets first look at the smaller box. 7 x 7 is 49 so we have that answer. then 7 x 20 is 120. add those together and you get 169.

The area of the composite figure is 189 square meters.

Step-by-step explanation:

First, partition the composite figure into 2 distinct shapes: a rectangle and a square on the top.

The formula for finding the area is: A = lw, or Area = length * width.

Area for figure number 1 (the square): 7 * 7 = 49

Area for figure number 2 (the rectangle): 20 * 7 = 140

Now, just add up both figures' areas, and find the

140 + 49 = 189

I hope this somewhat helped. Have a great day!

use formula for the circle a=3.14

step-by-step explanation:

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.
