The perimeter of a rectangular field is 82m and its area is 400m find the dimensions of the field |
|
Answer» Let breadth be Bperimater = 2(L+B)but perimeter=82,therefore , 2(L+B) = 82L+B = 41therefore L = 41- B.area = L* Bbut area given = 400m2so, L*B = 400B *(41-B) = 400-B2 + 41B = 400-B2 + 41B - 400 = 0B2 - 41B +400 = 0(MIDLLE TERM FACTORISATION)B2 - (25B+16B) +400 = 0B2 - 25B -16B +400 = 0B(B -25) - 16(B - 25)= 0THEREFORE BREADTH AND LENGTH ARE EITHER25 AND 16 RESPECTIVELY OR 16 AND 25 RESPECTIVELY.

Prove that ,Sin A(1+tanA)+cosA(1+cotA)=(secA+cosecA) |
| Answer» sinA(1+tanA)+cosA(1+cotA)=secA+cosecA.....solving LHS first....sinA(1+sinA/cosA)+cosA(1+cosA/sinA) [since we know that tanA =sinA/cos/A and cotA=cosA/sinA]=sinA(cosA+sinA/cosA)+cosA(sinA+cosA/sinA)=sinA+cosA{sinA/cosA+cosA/sinA}.....[taking sinA+cosA as common]=sinA+cosA(1-cos^2A+cos^2A)/sinA•cosA=(sinA+cosA)/(sinA•cosA)........now solving RHS.....secA+cosecA=1/cosA+1/sinA=(sinA+cosA)/(sinA•cosA).... Since LHS=RHS....Hence proved..?? | |
