A) 23.80
B) 30.60
C) 35.70
D) 40.80

Answer 1

Answer:

You will spend $35.70 .

Step-by-step explanation:

Plan to build an outdoor playpen contains 1 rectangle and 2 right angled triangles

Length of rectangle = 6 feet

Breadth of rectangle = 3 feet

Area of rectangle = $Length \times breadth = 6 \times 3 = 18 ft^2$

Height of triangle = 3 feet

Base = 1 feet

Area of triangle = $\frac{1}{2} \times Base \times Height =\frac{1}{2} \times 1 \times 3 = 1.5 feet^2$

Area of another triangle is same as it has same base and same height

So, Total area = 18+1.5+1.5 = 21 sq/feet

Cost of grass of 1 sq.feet = $1.70

Cost of grass of 21 sq.feet = $1.70 \times 21=35.70$

Hence You will spend $35.70 .

Answer 2

The answer is c because three times three is nine multiplyed by one is nine times six
