Answer:
Step-by-step explanation:
(-3,5) and (2,-5)
Slope m = (y2 - y1)/(x2 - x1)
y2 = -5, y1 = 5, x2 = 2, x1 = -3
m = (-5 - 5)/(2 + 3)
m = -10/5
m = -2
Slope = -2

Answer:
735 cm²
Step-by-step explanation:
The figure is a trapezium .The area of the triangle section can be calculated using the Heron's formula.
The other part of the figure will be a square of sides 21 cm by 21 cm
<u>Area of the square section</u>
Area = l²
Area = 21* 21 = 441 cm²
<u>Area of the triangle using Heron's formula</u>
Sides of the triangle are ;
a= 28 cm
c= 35 cm
b = 21 cm -----height of the trapezium
The Heron's formula is given as;

where s is half the perimeter of the triangle
Perimeter of the triangle is given as ;
P= 35 + 28 + 21 =84 cm
s= 84/2 = 42 cm

Total area = 294 + 441 = 735 cm²
Answer:
4t+6
Step-by-step explanation:
To find the perimeter of the rectangle you add the length of the sides.
Perimeter= t+ t+ t+ 3+ t+ 3= <u>4t+6</u>
or
Perimeter=2(t)+ 2(t+3)= 2t+ 2t+ 6= <u>4t+6</u>
