Answer:
Length = 6 cm and width = 4 cm.
Step-by-step explanation:
Let the width be x, then the length is x + 2 cm and its area = x(x + 2).
The new width and length are x + 4 and x + 6, and the new area is
(x + 4)(x + 6).
So we have the equation:-
(x + 6)(x + 4) = x(x + 2) + 56
x^2 + 10x + 24 = x^2 + 2x + 56
10x - 2x = 56 - 24
8x = 32
x = 4 cm = width
and length = 4 + 2 = 6 cm
The value of x is 5

Answer:
- The angles do not share a special relationship.
Step-by-step explanation:
Angles 13 — 20 are right angles. Angle 12 is complementary to given angle 7, so is 90°-72° = 18°. Angle 10 is vertical with angle 12, so is also 18°.
There is no special relationship between right angle 14 and acute angle 10.
