Question

A greeting card has an area 90 cm squared . between what two whole numbers is the length of its side ?​

Answer 1

Step-by-step explanation:

Given A greeting card has an area 90 cm squared ,between what two whole numbers is the length of its side ?

• Given area of greeting card is 90 cm^2
• So side^2 = 90 cm^2
• Now taking factors we get
• Side^2 = 2 x 3 x 3 x 5
• So side = √2 x 3 x 3 x 5
•              = 3 √10 cm
• So side = 9.486 cm

Therefore side lies between 9 and 10 whole numbers.

Answer 2

QUESTION:–

A greeting card has an area 90 cm squared . between what two whole numbers is the length of its side ?

GIVEN:–

area of greeting card=90cm²

SOLUTION:–

side²=90²0

now,by taking factors we get,side²=2×3×3×5

so side=√2×3×3×5

=3√10

=9.486

Therefore,side lies between 9 and 10 whole numbers.
