Answer:
Given : A rectangle is 6cm. longer than it is wide.
Its area is 187 sq.cm.
Required : To find the dimensions of the rectangle.
Solution : Let the width “w” = x cm.
Then the length “l” = (x + 6) cm.(given)
The area = “l” × ”w” ,
Substituting the assumed values of “w” and ”l” respectively, we have
The area = (x + 6) × x, and this equals to 187sq.cm(given).
Therefore, (x + 6) × x = 187……#1.
x^2 + 6x = 187.
x^2 + 6x + 9 = 187 + 9.

Answer:
14cm²
Step-by-step explanation:
given, l = 6cm and b = 2 (1/3) cm = 7/3 cm
=> area = 6 * (7/3) cm²
= (6*7)/3 cm²
= 2*7 cm²
= 14 cm²
