Answer question 8,9 and 10 with full details.

See Explanation

Step-by-step explanation:

8. (1)

Area of trapezoid = 1/2(sum of || sides) *perpendicular distance

36 =1/2(x+ y) * 6

36 = ((x + y)*3

36/3 = x + y

12 = x + y

x + y = 12.... (1)

8(2)

It is given that:

x = 2y....(2)

From equations (1) & (2)

2y + y = 12

3y = 12

y = 12/3

y = 4

From equation (2)

x = 2y = 2*4

x = 8

9.

Area of square = 1 square m

Side of square = 1 m

Area of circle = 1 square m

A=19.6 sqr. in.

Step-by-step explanation:

For a circle:

A=(Pi)r^2

d/2=r --> 5/2=2.5

A=(Pi)2.5^2

A=(Pi)6.25

A=19.625 --> rounded: A=19.6 sqr. in.
