Answer:

area = 960cm^2

Step-by-step explanation:

Perimeter = 2 x (length + width) ------(1)

Perimeter = 124cm

Let length be x

Given width is 2cm shorter than length , that width = x -2

    Perimeter = 2 (x + (x -2))\\\\124 =  2(x +x -2)\\\\62 = 2x -2 \\64 = 2x\\x = 32

Length = 32cm

Width = 32 - 2 = 30cm

Area = length x width

  = 32 \times 30 = 960cm^2

Rectangle Perimeter = 2 Length x 2 Width
Perimeter = 124cm
Length = L
Width = L-2
2 Length = 2 L
2 Width = 2 L - (2x2)
=2 L - 4

=124cm - 4cm
= 120cm
=120/4
=30cm
Width= 30cm
Length = 30cm + 2cm
= 32

Perimeter:
=2 x 32cm + 2 x 30cm
=64cm + 60cm
= 124cm

A plot of land has been surveyed for a new housing development with borders AB, BC, DC, and DA. The plot of land is a right trap
sdas [7]

Answer:

m∠ABC = 119° and DC = 105 feet

Step-by-step explanation:

For better understanding of the solution see the attached figure of the trapezium ABCD :

m∠BCD = 61°

By using the property, Sum of interior opposite angles in a trapezium is supplementary ⇒ m∠BCD + m∠ABC = 180°

⇒ m∠ABC = 180° - 61°

⇒ m∠ABC = 119°

Now, to find length of DC,

Draw a perpendicular BE on CD ⇒ CD = DE + EC

AB = DE

⇒ DE = 80 feet

In ΔBEC, By using Pythagoras theorem

EC² = BC² - BE²

⇒ EC² = 65² - 60²

⇒ EC = 25 feet

Hence, DC = 80 + 25

                   = 105 feet
