Find the area of the trapezoid. Pls explain and I will mark brainliest.

timama [110]

Answer:

B. 191.4 m²

Step-by-step explanation:

Split the trapezoid as pictured below

Find its height and the upper base, then find the area of the trapezoid.

There are 3 pieces, two of them are 45°×45° and 30°×60°×90° triangles

The ratio of sides of a 30°×60°×90° triangle is 1 : √3 : 2
The legs of a 45x45 triangle are equal

<u>The above mentioned properties give us:</u>

h = 16/2 = 8 m
b = 8√3 ≈ 13.85 m
a = h = 8 m

<u>Now find the area:</u>

A = 1/2( 13 + 8 + 13.85 + 13)*8 = 191.4 m²

Correct choice is B

PLEASE ANSWER ASAP WILL MARK BRAINLIEST

katrin2010 [14]

Answer:

48 hats and 104 shirts

Step-by-step explanation:

These are the equations you build from the problem:

h + s = 152

8.50h + 12s = 1656

This is how I solved them:

s= 152-h

8.5h + 12(152-h) = 1656

8.5h + 1824 - 12h = 1656

Solve for h

h= 48

Put this into first equation (h +s = 152) to get s

The pyramid shown has a height of 14 inches and a base area of 60 in2. Find the volume of the pyramid.

Kamila [148]

Volume of pyramid is $280 in^{3}$ .

The pyramid has a height 14 inches and a base area of 60 in2.

What is volume?

Volume is a three - dimensional quantity that is used to measure the capacity of a solid shape.

Volume of the pyramid = $Area base$ X $\frac{height}{3}$

= $60.\frac{14}{3}$

= $280$ $in^{3}$

So the volume of pyramid = $280$ $in^{3}$
