What's the area for number 5 and 6

So to find the area of a Triangle you want to use the equation:

A=B*H/2.

So for the base we use 18 and for the Height we use 8.

Then just do the equation. A=18*8/2=72in.

So to find the area of a Trapezoid you want to use the equation:

A=1/2h(b₁+b₂)

So the numbers we will be using is: 7,7,15.

Put the numbers in the equation: A=1/2(7)(7+15).

Then just do the equation. A=1/2(7)(7+15)=77yards

Find the value of x.
aleksandr82 [10.1K]

the sum of all interior angles in a polygon is

180( n - 2)

n = number of sides

now, this polygon is a quadrilateral, so it has 4 sides, so it's total is just 180( 4 - 2) = 360.

360=x+4x+3x+2x\implies 360=10x\implies \cfrac{360}{10}=x\implies 36=x

Need help with working perimeter and area please
SVETLANKA909090 [29]

Answer:

Area = 228 m²

Perimeter = 60 m

Step-by-step explanation:

The figure given shows a rectangle that has a cut triangular portion.

✔️Area of the figure = area of rectangle - area of the triangular cut portion

= L*W + ½*bh

Where,

L = 20 m

W = 12 m

b = 20 - (8 + 8) = 4 m

h = 6 m

Plug in the values

Area = 20*12 - ½*4*6

Area = 240 - 12

Area = 228 m²

✔️Perimeter = perimeter of rectangle - base of the triangular cut portion

= 2(L + W) - b

L = 20 m

W = 12 m

b = b = 20 - (8 + 8) = 4 m

Plug in the values

Perimeter = 2(20 + 12) - 4

= 2(32) - 4

= 64 - 4

Perimeter = 60 m
