Question

liliana makes a number 1 by cutting out a parallelogram and a rectangle. find the area of the number 1. area = in²

Explanation:

Step1: Calculate area of parallelogram

The formula for the area of a parallelogram is $A = base\times height$. Here, the base of the parallelogram is $5$ in and the height is $2$ in. So, $A_{1}=5\times2 = 10$ in².

Step2: Calculate area of rectangle

The formula for the area of a rectangle is $A = length\times width$. The length of the rectangle is $11$ in and the width is $3$ in. So, $A_{2}=11\times3=33$ in².

Step3: Calculate total area

The total area of the number - shaped figure is the sum of the area of the parallelogram and the area of the rectangle. $A = A_{1}+A_{2}=10 + 33=43$ in².

Answer:

43
