Question

the area of rectangle is 1936sq.m if the length of the rectangle is 4 times its breadth find the dimensions of the rectangle

Answer 1

Hello !!!


Let breadth of rectangle be X m.

Length = 4X m



Area of rectangle = 1936


L × B = 1936

4X × X = 1936



4X² = 1936

X² = 1936/4 = 484


X = ✓484 = 22 m



Breadth of rectangle = X = 22 m


And,

Length of rectangle = 4X = 4 × 22 = 88 m

Answer 2

Let breadth=x
Length=4x
Area=1936 sq.cm
lengthxbreadth=1936
4x*x=1936
4x²=1936
x²=1936/4
x=sqroot(484)
x=22
Length=4x=4*22=88 cm
Breadth=x=22 cm
