Question

Please give me answer its PISA test please give me​

Answer 1

• Equable rectangle: an equable rectangle has its perimeter and area numerically equivalent.

Solution:

Given that, x cm and y cm are length and width respectively of the rectangle.

Then its

• perimeter = 2 (x + y) cm
• area = xy sq. cm
• Given, x = 10 cm

Since the given rectangle is equable, we write:

• 2 (x + y) = xy
• or, 2 (10 + y) = 10y
• or, 10 + y = 5y
• or, 5y - y = 10
• or, 4y = 10
• or, 2y = 5
• or, y = 2.5

Therefore, the value of y is 2.5 cm.

Option (c) 2.5 centimetres.

Equable rectangle: an equable rectangle has its perimeter and area numerically equivalent.

Solution:

Given that, x cm and y cm are length and width respectively of the rectangle.

Then its

perimeter = 2 (x + y) cm

area = xy sq. cm

Given, x = 10 cm

Since the given rectangle is equable, we write:

2 (x + y) = xy

or, 2 (10 + y) = 10y

or, 10 + y = 5y

or, 5y - y = 10

or, 4y = 10

or, 2y = 5

or, y = 2.5
