Question

Frame the equation for the given condition using one variable:
a) The length of rectangle is twice its breadth. The perimeter of the rectangle is 36 cm.
b) The measure of an angle is one fourth the measure of its supplementary angle.​

Answer 1

Answer:

a) 2(2x + x) = 36 cm

b) 4x + x = 180 degrees

Step-by-step explanation:

a) Let the length and breadth be 2x and x respectively

Therefore, Perimeter = 2(2x + x) = 36 cm

b) Let, the smaller angle be x

Therefore, bigger angle = 4x

ATQ, 4x + x = 180 degrees
