Rectangle 79084

A rectangle whose one side measures 35m and the other is 7m shorter than the diagonal of the rectangle. Calculate the content in m2.

Correct answer:

S =  2940 m2

Step-by-step explanation:

a=35 m b = u 7  m  u2 = a2 + b2  u2 = a2 + (u7)2  u2 = 352 + (u7)2  14u1274=0  14 u1274=0  14u=1274  u=141274=91  u=91  b=u7=917=84 m  S=a b=35 84=2940 m2
