Answer: 75 square
Explanation:
Width is X
Length is 3x
Every rectangle has 2 equal widths x 2 equal lengths
Perimeter is 2x + 2(3x) = 40
X = 5
Width is now 5in
Length is now 15in
Area is 75in^2
Half of a perimeter is length + width, which equals to 20in
4x = 20, CX = 5
= 75 sq

-----> by central angle
see the attached figure to better understand the problem
we have
substitute
Answer:
4 cm
Step-by-step explanation:
The figure is a parallelogram with area (A) calculated as
A = bh ( b is the base and h the perpendicular height )
Here A = 36 and b = 9 , thus
9h = 36 ( divide both sides by 9 )
h = 4 cm
