Calculate the area of a rectangular field with perimeter 88 cm and length 18 cm​

Mathematics

The area of the rectangular field is 468cm².

Step-by-step explanation:

If, length is 18cm; width is unknown( let x represent width). Then,

<u>Perimeter of a rectangle</u>= Length + Width+ Length + Width

88= 18 + x + 18 + x

88= 36 + 2x

88-36 =2x

52= 2x

52/2=2x/2

26=x

•x=26cm

<em>The</em><em> </em><em>width</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>rectangle</em><em> </em><em>is</em><em> </em><em>2</em><em>6</em><em>c</em><em>m</em><em>.</em>

<u>Area of a rectangle</u>= Length × Width

=18cm×26cm

= 468cm².

Answer:

x=17

Step-by-step explanation:

Since the triangles are congruent, the angles are equal

I≅ P  

3x+4 = 72-x

Add x to each side

3x+4+x = 72-x+x

4x+4 = 72

Subtract 4 from each side

4x+4-4 = 72-4

4x= 68

Divide by 4

4x/4 = 68/4

x = 17

Slope = ( 7+2)/(0 - 8) = -9/8
b = 7
equation
y = -9/8 x + 7

-------------------------------------
(-2,0)(0,-2)
slope = (0 +2)/(-2 - 0) = -1
-------------------------------
y = -2x
x = 0 y = 0
x = 1 y = -2
x = -1 =  2
