Question

work out the are of the rectangle when base=38mm and peremeter =100mm

Answer 1

Answer:

2(l+b)

2(x +38) =100

x =62

Answer 2

Answer:

Step-by-step explanation:

Given:

Base or Breadth,

38mm.

Perimeter,

100 mm.

To find:

Area of the rectangle,

Solution:

To find area we need length and breadth,

Breadth is given so to find length substitute the values in perimeter of rectangle,

Calculation:

Take length as x,

As,you know perimeter of rectangle=2(l+b),

2(38+x)=100,

76+x=100,

x=100-76,

x=24 mm,

So length = 24 mm.

Area=l×b,

Substitute the values given,

Area=38×24,

912 mm²,

So,the area of theee rectangle=912 mm².

Hope it helps.
