Question

kathy is looking to fill a part of a park with sand. the shape below represents the part of the park being covered in sand. how many square yards of the park will kathy cover in sand? solve on paper if you need to. then, enter your answer on - screen. kathy will cover square yards of the park with sand.

Explanation:

Step1: Identify shapes

The figure is composed of a rectangle and a triangle.

Step2: Calculate rectangle area

The area formula for a rectangle is $A = l\times w$. Here, $l = 10$ yd and $w=10$ yd, so $A_{rectangle}=10\times10 = 100$ square - yards.

Step3: Calculate triangle area

The area formula for a triangle is $A=\frac{1}{2}\times b\times h$. Here, $b = 8$ yd and $h = 10$ yd, so $A_{triangle}=\frac{1}{2}\times8\times10=40$ square - yards.

Step4: Calculate total area

The total area $A = A_{rectangle}+A_{triangle}$. So $A=100 + 40=140$ square - yards.

Answer:

140
