The length of a rectangle is 3 cm longer than its width. if the perimeter of the rectangle is 46 cm , find its area.

1 answer:

7 0

A) L = W + 3
B) 2L + 2W = 46
Putting equation A into B
2 * (W+3) + 2W = 46
2W + 6 + 2W = 46
4W = 40
Width = 10
Length = 13

Area = Length * Width
Area = 13 * 10
Area = 130 square centimeters

Complete Question:

A colony of flowers is pollinated by hummingbirds and sunbirds. Let H represents the number of hummingbirds and S represent the number of sunbirds that must pollinate the colony so it can survive until next year.

6H+ 4S> 74

This year, 8 hummingbirds pollinated the colony. What is the least number of sun birds that must pollinate the colony to ensure that it will survive until next year?

Answer:

The least number of sun birds is 7

Solution:

Given inequality is:

6H + 4S > 74

Where,

H is the number of hummingbirds

S is the number of sunbirds

This year, 8 hummingbirds pollinated the colony

Substitute H = 8 in given inequality

6(8) + 4S > 74

48 + 4S > 74

Subtract 48 from both sides

48 + 4S - 48 > 74 - 48

4S > 26

Divide both sides by 4

S > 6.5

Hence the least number of sun birds is 7
