Answer:

50 feet

Step-by-step explanation:

Perimeter is the sum of all of the lengths of the sides.

A triangle has three sides, and three lengths are given, therefore all the sides are given.

The sum of the sides is 20 + 20 + 10 = 50

So the Perimeter is 50 feet

1. To solve this exercise, you must apply the formula for calculate the area of a trapezoid, which is shown below:

A=(b1+b2/2)h

A is the area of the trapezoid.
 b1 is the larger base of the trapezoid (b1=16-4=12 ft).
 b2 is the smaller base of the trapezoid (b2=10-4=6 ft).
 h is the height of the trapezoid (h=12-4=8 ft)

2. When you substitute these values into the formula A=(b1+b2/2)h, you obtain:

A=(b1+b2/2)h
 A=(12 ft+6 ft/2)(8 ft)
 A=9 ftx8ft
 A=72 ft²

3. The length of fencing is: a²=b²+c² a=√b²+c² a=√(8 ft)²+(6 ft)² a=10 ft Perimeter (Length of fencing)=12 ft+8 ft+6 ft+10 ft=36 ft

The area of a rectangle garden is 2g^2+34g+140. If the width is 2g+14 what is the length?

ASHA 777 [7]

We know that
[area of rectangle]=length*width
area=2g²+34g+140
width =2g+14

step 1
find the roots of 2g²+34g+140

using a graph tool-----> to resolve the second order equation
see the attached figure
the solution is
g=-10
g=-7
so
2g²+34g+140=(2g+14)*(g+10)

therefore

the length is (g+10)

the answer is
the length is (g+10)

7. If the concert handed out 208 wands and some wands were red wands and some were green wands. The ratio of red wands to green

umka21 [38]

Answer:

red = 52

Green = 156

Step-by-step explanation:

The 208 has to be divided by 4.

Three wands = 3 parts

The read wands = 1

3x + x = 208 Combine terms

4x = 208 Divide by 4

x = 208/4

x = 52

Now the red wands = 52

The Green wands =156 (3 times 52)

Total 208 Just as it should
