A rectangle has a 60m perimeter. If its length is twice its breadth, what is its area__________?
Show answer Hide answer
Answer: C. 200m2
Explanation
The perimeter of a rectangle is equal to twice the sum of its length and breadth. Given the perimeter is sixty meters and length is twice breadth, dimensions evaluate to twenty and ten. Multiplying length by breadth yields an enclosed area of two hundred square meters. Rectangle perimeters measure the total distance around the outer boundary of the shape. Length to breadth ratios allow simplifying perimeter equations into single variable expressions. Area is calculated as the product of perpendicular length and breadth dimensions.
Construction planning requires calculating floor areas from known perimeter and proportion constraints. Real estate professionals use perimeter and area dimensions to evaluate property sizes. Basic geometry connects linear boundary measurements with two dimensional space calculations. Option a suggests one hundred sixty square meters which underestimates the correct calculated area. Option b proposes one hundred eighty square meters due to an incorrect dimension calculation. Option d overestimates the area by calculating with incorrect side length values.
