Answer:

128

Step-by-step explanation:

First, I cut this rectangle in half vertically, right through the middle.

To find the area of an rectangle, multiply length by the height

Left rectangle area : 8*10 = 80 ( 8 is the height and 10 is the length)

Right rectangle area: 8*6 = 48 (8 is the length and 6 is the height)

Add the lengths together : 80+48= 128

The area of this rectangle is 128

where

b is the length side

we have

$b=3.5\ m$

substitute

$A=3.5^2=12.25\ m^2$

Part 2) Determine the perimeter

we know that

The perimeter of a square is given by the formula

$P=4b$

where

b is the length side

we have

$b=3.5\ m$

substitute

$P=4(3.5)=14\ m$
