Roman55 [17]

Answer:

64\ \text{sq. units}

Step-by-step explanation:

Area of a rhombus is the product of the length of the diagonals divided by two.

Length of one diagonal is 8 units and the other diagonal is 16 units

Area is given by

A=\dfrac{8\times 16}{2}\\\Rightarrow A=64\ \text{sq. units}

The area of the rhombus is 64\ \text{sq. units}

Another approach is the diagonals have created 4 triangles where the base and is height is either 4 units long or 8 units long so the area of the rhombus would be the area of the 4 triangles.

A=4\times \dfrac{1}{2}\times 4\times 8\\\Rightarrow A=64\ \text{sq. units}

Dmitrij [34]

Answer:

let x be no. of 4-wheel and y be no. of 3-wheel ATVs

so

x+y=17 (each has one set of handlebars)

4*x + 3*y = 61

4*(x)+3*(17-x)=61

x=61-51=10

y=17-10=7

thus x=10 and y=7 and that's your answer
