Answer:
A) 35 in
Step-by-step explanation:
Area of rhombus is equal to product of its diagonals divided by 2.
(10in * 7in)/2 = 35in
Answer:
The answer is 40 sq. units
That is: 1/2×b×h (formula for area of triangle)
1/2×10×8
= 40
Answer:
24 m
Step-by-step explanation:
The lenght of fencing needed is the sum of all sides the triangular garden represented on the coordinate grid.
The lenght of the triangular garden = 16 - 10 = 6 m
Lenght of the height = 8 - 0 = 8 m
Lenght of the hypotenuse can be calculated using coordinates of the two vertices of the ∆ that forms the hypotenuse lenght and also using the distance formula.
Coordinates of the two vertices = (10, 0) and (16, 8).

Let,





Length of fencing = 6 + 8 + 10 = 24 m
Graph A.....parallel lines will have no solution because they never intersect
