Answer:

Area of shaded part ABCEF = 66 sq.cm

Step-by-step explanation:

AB = 8cm

CD = 8cm

Let DE = x cm

CE = 3x cm

CD =  CE + DE = 8cm

        x + 3x = 8

4x = 8

x = 8/4 = 2 cm

DE = 2cm

CE = 3 * 2 = 6 cm

Area of triangle ADE = 1/2 * base * height

                                   = 1/2 * DE * AD

                                    = 1/2 * 2 * 11 = 11 sq. cm

Area of triangle AEF = Area of triangle ADE = 11 sq. cm

Area of Rectangle ABCD =  l * b = 8 * 11 = 88 sq.cm

Area of shaded part ABCEF =  Area of Rectangle ABCD - (Area of triangle AEF + Area of triangle ADE)

    = 88 - ( 11 + 11 )  = 88 -22 = 66 sq.cm

–3х - 7y = 8<br> 3х - 2y = 44
lara31 [8.8K]

Answer:

  • One solution

Kind Note:

This question is incomplete. You need to provide the question in order to get the best answer on brainly. In this answer, I will tell you how many solutions are in this system of equations.

Step-by-step explanation:

This question involves the use of 'system of equations'.

  • => -3x - 7y = 8

             3x - 2y = 44

  • => (-3x + 3x) + (-7y - 2y) = (8 + 44)
  • => -9y = 52
  • => y = -52/9 (No further check required)

Since the y-intercept is valid, the system of equations has one solution.

Hence, this system of equations has one solution.

Hoped this helped!

Charra [1.4K]

Answer: He will need 8 gallons of paint for the other murals.

Step-by-step explanation:

Given: 1 gallon of paint was required to create 1 mural.

Since replicates have the same dimensions, i.e same total surface area.

So, if 8 replication need to be made, the quantity of the paint required for this will be

8  x (Quantity required for 1 mural)

= 8 x 1

= 8 gallons

Hence, he will need 8 gallons of paint for the other murals.
