Question

the area of a rectangle is 12 whole 7/4. if the measure of its length is 7/12 m, then find its breadth also, find perimeter.​

Answer 1

Explanation:

Area of rectangle = l×b = lb

Area = 12 whole 7/4 m² = 55/4 m²

Length = 7/12m

Breadth = ?

Length × Breadth = 55/4 m²

7/12m × Breadth = 55/4 m²

Breadth = A/L = 55/4m² divided by 7/12m

= 55/4m²×12/7 m = 165/7m = 23 whole 4/7m

Answer 2

Answer:

Perimeter of the given rectangle is a + b + a + b. Since opposite sides of a rectangle are always equal, we need to find the dimensions of only two sides to find the perimeter of a rectangle. The perimeter of the above rectangle with sides 'a units' and 'b units' is: a + b + a + b = 2a + 2b = 2 (a + b) units.
