Question

find the area of rhombus with p=100 and a diagonal of 48

Answer 1

what is p?

Answer 2

Area of a rhombus is given by: \(\frac 12 \times\) Product of the diagonals.

Answer 3

perimeter

Answer 4

what do i do with the perimeter

Answer 5

If P is the perimeter then P/4 is the length of the one side right?

Answer 6

yeah 25

Answer 7

i don't understand what to do with that

Answer 8

Okay, There is a property relating side and the two diagonals of a rhombus:

side\( ^2 \) = ( \(\frac12\times \) one diagonal)\(^2\) + (\(\frac12\times \) other diagonal)\(^2\)

So, you can use this to find the length of the other diagonal and then use it to find the area.

Answer 9

so one diagonal would equal 96

Answer 10

One diagonal is 48 which is given and the other should be 14. Area = 336 sq units.

Answer 11

Does it help?

Answer 12

how did you get 14?

Answer 13

Set x = the other diagonal, now using the formula
