The length of a rectangle is (x+3)cm. If the width of the rectangle is two thirds its length and the perimeter is 27cm, find its area

Step-by-step explanation:

Represent Length with L, Width with W and Perimeter with P

Required

Determine the Area

From the perimeter, we need to solve for x;

Substitute values for P, L and W

Collect Like Terms

Open bracket

Collect Like Terms

Solve for x

The Area is then calculated using:

Substitute 5.1 for x

Hence, the area is

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
