Find the area of the trapezoid.

Usimov [2.4K]

Answer:

$\large\boxed{A=54\ m^2}$

Step-by-step explanation:

The formula of an area of a trapezoid:

$A=\dfrac{b_1+b_2}{2}\cdor h$

b₁, b₂ - bases

h - height

We must use the Pythagorean theorem:

$x^2+8^2=10^2$

$x^2+64=100$ subtract 64 from both sides

$x^2=36\to x=\sqrt{36}\\\\x=6\ m$

We have b₁ = 6 + 6 = 12m, b₂ = 6m and h = 8m.

Substitute:

$A=\dfrac{12+6}{2}\cdot6=\dfrac{18}{2}\cdot6=(9)(6)=54\ m^2$

The circumference of the circle-shaped rug is 56.52 inches. What is the area of the rug?

Elena-2011 [213]

56.52 ÷ pi(3.14) = 18

18 ÷ 2 =9

A = pi(3.14)r^2
A = 3.14 × 9^2
A = 3.14 × 81
A = 254.34in^2

Tom and Jerry went out for dinner. They ordered a nice meal and their bill was $300 . They also paid 15% tax on there bill. What

ELEN [110]

45, right? 300 plus the 15 percent which is .15, so we multiply that to 300 and we get 45. So in total they paid 345. Was Jerry Tom's snack?
