Answer:
Width = 4 cm
Step-by-step explanation:
The formula for area of a rectangle is length x width. You have the length (10), leaving you with this equation.
10 x ? = 40
Solve for x, or in other words, divide 40 by 10. This gives you 4. This means that 10 x 4 equals 40 cm^2
Answer:
76 square feet
Step-by-step explanation:
surface area = 2(wl + hl + hw) w=width h=height l=length
surface area = 2(5*4 + 2*4 + 2*5)
surface area = 2(20 + 8 + 10)
surface area = 2(38)
surface area = 76 square feet

<h3>What is the unitary method?</h3>
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Glurpina is a polymorph alien and can grow extra limbs.
She has 3 hands and can shake everyone's hand at the alien conference in 10 minutes.
She can shake everyone's hand by 3 hands in 10 minutes.
She can shake everyone's hand by 1 hands in 10 / 3 minutes.
She can shake everyone's hand by how many extra hands in 3 minutes.
= 3/ 10 x 3
= 9/10
Thus, She can shake everyone's hand by 9/10 hands in 3 minutes.
