The area of the rectangle is 0.0875 sq ft.

Step-by-step explanation:

Given that,

The length of the rectangle, L = 0.35 feet

The breadth of the rectangle, B = 1/4 feet

We need to find the area of the rectangle. The formula for the area of a rectangle is given by :

A = LB

Put all the values,

$A=\dfrac{1}{4}\times 0.35\\\\A=0.0875\ ft^2$

So, the area of the rectangle is 0.0875 sq feet.

Simora [160]

Answer:

In order to calculate perimeter, you need to add together the lengths of all four sides of the square. You are given the length of one side. Remember, all sides of a square are equal, so really you already have the measures of each side. Then, you add them together, so 6 + 6 + 6 + 6 = 24 inches.
