We have to calculate the area of the rhombus if AE = 20 m and DE = 32 m.The diagonals DB = 2 * DE and AC = 2 * AE.
DB = 2 * 32 = 64 mAC = 2 * 20 = 40 mArea = d1 * d2 / 2 = DB * AC / 2 = 64 * 40 / 2 = 1,280 m²Answer: The area of the rhombus is B ) 1,280 m².
Let x be the number of 52 cent stamps that Sally has and let y be the number of 34 cent stamps that she has.
Then,
52x + 34y = 1150 --- (1)
Also, she has six more 34 cent stamps than 52 cent stamps.
Therefore, y = x + 6
(1) becomes
52x + 34(x + 6) = 1150
52x + 34x + 204 = 1150
86x + 204 = 1150
86x = 1150 - 204
86x = 946
x = 11
and y = 11 + 6 = 17
Hence, Sally has eleven 52 cent stamps and seventeen 34 cent stamps.
