Question

the length of a rectangular mat is twice its breadth if its length is 50 cm,
a.find area and perimeter
b.find the cost of embroidering it at RS 5 per cm square
c. find the cost of bordering it at rs 3.50 per cm​

Answer 1

Answer:

a. Area = 1250 cm^2,Length = 150 cm , b. Rs 6250 , c. Rs 525

Step-by-step explanation:

Let the breadth be x.

Length = 2x = 50cm

x = 50 ÷ 2

x = 25 cm

a. Area of the rectangular mat = length × breadth

= 50 × 25

= 1250 cm^2

Perimeter of the rectangular mat = 2 (length + breadth)

= 2(50 + 25)

= 2 × 75

= 150 cm

b. Cost of the embroidering at it per square cm = Rs 5

Area of the rectangular mat = 1250 cm^2

Cost of the embroidering on full mat = 1250 × 5

= Rs 6250

c. Cost of bordering per cm = 3.5

Perimeter of the rectangular mat = 150 cm

Cost of bordering full mat = 3.5 × 150

= Rs 525
