Answer:
24 cm squared
Step-by-step explanation:
cut the dotted line and move the new triangle to the other side this makes a square 4*6=24 cm squared.
First term(a)=2
D=8
Now
t13=a*12D
=2*12*8=192
Answer= 192
First let us represent
x-width
x+3-length
Since it has a width and length, we can say it is a rectangle so the formula for the perimeter of it is 2(l+w)
p=2(l+w)
58=2(x+3+x)
58=(2x+3)2
58=4x+6
52=4x
x=13
the width is 13 and the length is 16
Well, it wouldn'r be a square, but a rectangle.
3*7=21
The area of the rectangle is 21u²
