This is the area of a triangle and a square
Area of a triangle is 1/2BH
here total height is 16 in triangle h is 16-10=6
base is 10
A=1/2*10*6
A=30 inch^2
Area of square=a^2
A2=10^2=100inches^2
A1+A2=100+30
130inches^2
Answer:
Width=5m
Lenght= 20m
Step-by-step explanation:
L= Lenght
W= width
perimeter = (2L + 2W) ......eqn(1)
From the question, length of the rectangle is 4 times of it's width
Then
L = (4W)........eqn(2)
But perimeter = 50
Fromeqn(1)
(2L + 2W)= 50........eqn(3)
Sub eqn(1) in eqn(3)
2(4W) + 2W = 50
8W + 2W= 50
10W= 50
W=5
From (1)
L = (4W)
L= 4×5= 20
Lenght= 20
They would have sold 21 burgers with out chesse because 21 is 7/10 of 30 hope I helped
4y-17=43
move -17 to the other side
sign changes from -17 to +17
4y-17+17=43+17
4y=43+17
4y=60
divide both sides by 4 to get y by itself
4y/4=60/4
answer:
y=15
