C prices in a store cause it has 2 sets of numbers the prices
hi <3
439.612, 439.261, 439.216, 439.126
hope this helps :)
Step-by-step explanation:
Left side: 18cm
Under that: 5cm
5cm again
Perimeter = 76
Because: 20 + 18 + 18 + 5 +5 +5 +5 = 76
It helps to draw diagrams when working through problems like this.
Given a rectangular prism (the suitcase), drawing a diagonal through its side will give you two right triangles. You can use the Pythagorean Theorem (a² + b² = c², where c is the hypotenuse of a right triangle) to find the length of the unknown side. The hypotenuse of the triangle is the diagonal since it is the longest side, and it is opposite the right angle.
a² + b² = c²
a² + 24² = 26²
a² + 576 = 676
a² = 100
a = 10 in
Remember that this is only the side length of the triangle. To find the amount of material needed to cover one side of the suitcase, we need its area. We can find the area using the formula for area of a rectangle: A = bh.
A = bh
A = 10*24
A = 240 in²
