Answer:Given a rectangle, the general equation for the perimeter is P=2l+2w and area is A=lw where l is the length and w is the width.
Let x = width and x+10 = length
So the equation to solve becomes 40=2x+2(x+10) so x=5 thus the width is 5m and the length is 15m.
Thus the area is 5⋅15=75m2
Step-by-step explanation:
Answer:
3 hours 39 minutes
Step-by-step explanation:
6 to 10 = 4 hours
35 to 14 = -21
4 x 60 = 240
240 - 21 = 219
220 to hours and minutes = 3 hours and 39 minutes

Answer:
1.) Step-by-step In mathematics, the Pythagorean theorem, or Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides. This theorem can be written as an equation relating the lengths of the sides a, b and c, often called the Pythagorean equation:[1] 2
2.) Architecture and Construction. Given two straight lines, the Pythagorean Theorem allows you to calculate the length of the diagonal connecting them. This application is frequently used in architecture, woodworking, or other physical construction projects. For instance, say you are building a sloped roof.
