Answer:

  • length 32 cm
  • width 8 cm

Step-by-step explanation:

Let w represent the width. Then the length is 4w and the perimeter is ...

  P = 2(length +width)

  80 = 2(4w +w) = 10w . . . . substitute given values

  8 = w . . . . . . . divide by 10

  length = 4w = 4·8 = 32

The length is 32 cm; the width is 8 cm.

1.Which postulate or theorem can you use to prove Triangle ABE = Triangle CDE?
stira [4]

Answer:

AAS Postulate.

Step-by-step explanation:

The AAS Postulate states that if 2 angles and a non-included side are congruent on both triangles, then the two triangles are equivalent.

In this case, the first Angle is: ∠B ≅ ∠D (Given, both are 90° in measurement)

For the side: Line BE ≅ line DE (Given)

∡BEA ≅ ∡DEC (Definition of Vertical Angles)

AAS Postulate is therefore used.
