Question

Nessa is cutting construction paper into rectangles for a project she need to cut one rectangle that is 16 inches times 15 1/4 inches she needs to cut another rectangle that is 10 1/2" x 10 1/4" how many total square inches of construction paper does Nessa need for her project

Answer 1

Answer:

The total  square inches of construction paper  Nessa needs for her project is approximately 352 square inches

Step-by-step explanation:

To get the total area of cardboard Nessa needs, we will simply have to add the areas of the two rectangles together.

The first step is to calculate the area of the rectangle using the formula, Area = length X breadth

Area of first rectangle:

$A = 16 \times 15\frac{1}{4}= 16 \times \frac{61}{4} =244 in^{2}$

Area of the second rectangle :

$A = 10\frac{1}{2} \times 10\frac{1}{4} = \frac{21}{2} \times \frac{41}{4}=107.625 \approx 108 in^{2}$

The total  square inches of construction paper  Nessa needs for her project is 244 + 108 = 352 square inches
