Split the shape into two shapes

A square

Area = L x H = 20 x 21 = 240 cm2

A right angle triangle


Area of right angle triangle = L x H divided by 2

20 x 21 = 240 divided by 2 = 120 cm2

Add both areas

240 + 120 = 360 cm2

five less than a number is at least 40. write and solve an inequality to find the minimum value of the number​
mina [271]

Answer:

45

Step-by-step explanation:

5 less than your number is at least 40. Let the number be x. So rephrasing the statement, 5 less than x is greater than or equals 40.

x-5 ≥ 40

x-5+ 5 ≥ 40+5 (adding 5 to both sides to single out the x in LHS)

∴x   ≥ 45

In other words, x is at least 45.

Therefore, the minimum value of x is 45.
