Question

1. find the area of the given shape. area = enter your next step here cm²

Explanation:

Step1: Divide the shape into rectangles

We can divide the given shape into two rectangles. One rectangle with length 12 cm and width 4 cm, and another with length 9 cm and width 3 cm.

Step2: Calculate area of first rectangle

The area formula for a rectangle is $A = l\times w$. For the rectangle with $l = 12$ cm and $w = 4$ cm, $A_1=12\times4 = 48$ $cm^{2}$.

Step3: Calculate area of second rectangle

For the rectangle with $l = 9$ cm and $w = 3$ cm, $A_2=9\times3=27$ $cm^{2}$.

Step4: Calculate total area

The total area of the shape $A = A_1 + A_2$. So $A=48 + 27=75$ $cm^{2}$.

Answer:

75
