Question

*The area of a rectangle when its length is (x+2) cm and breadth is (x-5) cm is 60 sq. cm. The equation representing the information is ________.*

1️⃣ ²-3x-10=0
2️⃣ ²-3x-70=0
3️⃣ ²-7x-70=0
4️⃣ ²-7x-10=0​

Answer 1

$\huge\sf\pink{answer:}$

$\bf{Here,~we~know~that;}$

$\bf{formula~for~area~of~a~rectangle~is:}$

$\bf{l×b~~where~l~is~length~and~b~is~breadth}$

$\bf{Given~that:</p><p>l=(x+2)~~and~~b=(x-5)}$

$\bf{ \therefore The~equation~will~be:}$

$\bf{~~~~(x+2)(x-5)}$

$\bf{→x^{2}-5x+2x-10}$

$\bf{→{\blue{\underline{\boxed{\bf x^{2}-3x-10=0}}}}}$
