Solution

Given Here :-

the area of a RECTANGLE is 55/4 m²
Length = 7/12 m

Find :-

Breadth & perimeter of rectangle

Explanation

Using Formula

★ Area of rectangle = Length × Breadth

★perimeter of rectangle = 2 × (Length + Breadth )

Now, calculate Breath

For this, keep value of length & area in area of rectangle formula

➡ Area of rectangle = 7/12 × Breadth

➡ 55/4 = 7/12 × Breadth

➡ Breadth = 55/4 × 12/7

➡ Breadth = 55 × 3/7

➡ Breadth = 165/7 m

_______________________

Now, calculate perimeter

➡perimeter of rectangle = 2 × (Length + Breadth )

keep value of length & breadth

➡ perimeter of rectangle = 2 × (7/12 + 165/7)

➡perimeter of rectangle = 2 × ( 7×7+165×12)/(12×7)

➡perimeter of rectangle = 2×(59+1980)/84

➡perimeter of rectangle = 2 × 2029/84

➡perimeter of rectangle = 2029/42

➡perimeter of rectangle = 48.31 m

Hence

perimeter of rectangle will be = 48.31 m
