laminated.

a. Who has to pay more for framing and by how much, if the cost of framing is Rs 6 per

cm?

Answer 2

Answer:

for finding the case of framing,we need to find the perimeter and then multiply it by the rate of framing:

Step-by-step explanation:

In CASE OF AAYUSH

perimeter of the rectangular sheet= 2(l+b)

= 2(60+20) cm=2×80cm=160cm

cost of framing at the rate of ruppee 3 per cm

=ruppee (3×160)= ruppee 480

IN CASE OF DEEKSHA

perimeter of the rectangular sheet=3(l+b)

=2(40+35)cm=2×75 cm=150 cm

cost of framing at the rate of ruppee 3 per cm

=ruppee (3×150) cm

: ruppee 480>ruppee 450

so, Aayush has to pay more for the framing

for finding the cost of lamination,we need to find the area and then multiply it by the rate of lamination:

IN CASE OF AAYUSH

area of the rectangular sheet=(60×20) sq.cm

=1400 sq.cm

••• cost of lamination at the rate of ruppee 2 per sq.cm

=ruppee (2×1400) =ruppee 2800

thus,Deeksha has to pay more for the lamination

: ruppee 2800>ruppee 2400

for framing Aayush has to pay more

for lamination Deeksha has to pay more
